l/VINDOVf-SASH LOCK.

Application filed June 11, 1824. Serial No. 719,382.

To aZZ iii/mm only concern:

Be it known that I, ERNEST limits, at citizen of the United. States. residing at Fort \Vayne, in the county of Allen and State of Indiana, have invented certain new and use ful Improvements in a lVindow-Sash Lock, of which the following is a specification.

This invention relates to new and useful improvements in window sash locks and has for its principal object to provide a simple and eflicient means for locking a pair of sliding window sashes together in various adjusted positions.

A further object of the invention is to provide a window sash lock of the above mentioned character which will securely hold the window sashes in locked engagement with respect to each other, means being provided for preventing the locking means from becoming accidentally dise gaged when in use.

A still further object is to provide a window sash lock of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure l is a front elevation of my improved window sash lock showing the same in use, and

Figure 2 is a side elevation thereof.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numerals 1 and 2 designate the upper and lower window sashes, the same being adapted for slidable movement in the window casing 3 in the manner well known in the art. Secured to the upper sash 1 at oneside thereof is the vertically extending ratchet bar 4, the samethe upper sash 1 by means of. the fastening screws 5 in the manner clearly illustrated in the drawing. The ratchet bar is preferably secured to the upper sash adjacent the lower edge thereof.

Secured to the top of the lower sash 2 is the bracket 6, the same being secured to the-upper edge of the lower sash 2 at a point being secured to coincident with the ratchet bar 4. Pivotally supported on the bracket 6 adjacent the inner end thereof as illustrated at 7 is the locking dog 8, the free end of which is adapted for engagement with the ratchet teeth in the ratchet bar a. A shoulder such as is illustrated at 9 is provided on the back or rear portion of the locking dog intermediate the ends thereof and the purpose of this construction is to provide a means whereby the swinging wire catch 10 which is pivotally supported on the outer end of the bracket 6 in the manner clearly illustrated in Figure 2 of the drawing. The swinging catch 10 is formed of a single strand of wire, the central portion thereof being straight, the end portions being disposed at right angles to the straight portion and in parallel relation with respect to each other. The terminals or free ends of the wire are disposed inwardly and extend substantially parallel to the central straight portion of the wire as clearly illustrated in Figure 1. The inwardly extend ing terminals provide a means for pivotally supporting the wire catch on the bracket 6 and furthermore enables the swinging catch to be easily and readily assembled in position on the bracket.

Normally the locking dog 8 and the swinging wire catch 10 are in the position as shown in the dotted lines in Figure 2 of the drawing and the upper sash 1 and the lower sash 2 may be moved with re spect to each other so that the window may be opened at the top and bottom. After the sashes have been moved to the. proper adjusted positions, the locking dog 8 is swung on its pivot 7 so that the free end thereof will engage the ratchet bar 4 to hold the sashes in locked engagement with each other and to prevent the accidental displacement of the locking dog from engagement with the ratchet bar 4, the swinging wire catch 10 is moved into engagement with the shoulder 9.

It will thus be seen from the foregoing description, that a window sash lock has been provided which may be readily and easily operated for holding the upper and lower sashes of a window in various adjusted positions and the simplicity of my clevice furthermore enables the same to be readily and easily attached in position on windows of the sliding type without altering the construction of the same. A window sash lock of the character above described may be manufactured at a very low cost and will be strong and durable.

\Vhile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size,

shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claim.

Having thus described the invention,

what I claim is zcured to the top of the lower sash, a lock- .ing dog pivotally supported on the bracket and adapted for engagement with the ratchet bar, a shoulder formed on the back of the locking dog, and means cooperating with the shoulder for holding the lockingdog in locked engagement with the ratchet bar, said means comprising a swinging catch formed of a single strand of wire, the central portion thereof being straight, the ends of the Wire extending at substantially right angles to the central straight portion and parallel minals of the wire being disposed inwardly in arallel relation With respect to the centra straight portion for pivotally supporting the catch on the bracket.

and providing a means In testimony whereofl affix my signature.
